２・・・全体の温度は約５０℃となる。これらのフィン
２・・・に流入された２１℃の空気は約４８℃まで上昇
される。Hereinafter, the heat exchange state of the heat exchanger 20 during heating will be explained in comparison with a conventional structure. Since the heat exchanger 1 described in the conventional example has fins 2 integrally provided throughout, it is affected by the difference in temperature between the fins on the artificial side of the heating medium and the temperature of the fins on the outlet side. It remains almost constant. In other words,
When the temperature of the heat medium inlet 5 is about 90°C, the temperature of the entire fin 2 is about 50°C. The air at 21°C flowing into these fins 2 is raised to about 48°C.
こうした熱交換器１は、熱媒の流入口５と吐出口６とが
互いに近接して設けられているので、熱媒の流入側と吐
出側との間で熱交換をしてしまうものであった。In such a heat exchanger 1, the inlet 5 and the outlet 6 of the heat medium are provided close to each other, so that heat exchange occurs between the inlet side and the outlet side of the heat medium. Ta.

５Ｃで約５０℃、そして、吐出口２０で約４０℃となる
。On the other hand, the heat exchanger 10 has two suction ports 23
．． When the temperature of the heat medium sucked from the heat exchanger 24 is about 90°C as described above, the air at about 21°C flowing into the heat exchanger 10 is raised to about 50°C. The temperature of the heating medium is determined by the suction port 2.
3.24 and approximately 90°C. The temperature gradually decreases toward the discharge side. Approximately 60℃ with the above pipe 2a, vibrator 1
The temperature at 5C is approximately 50°C, and the temperature at the discharge port 20 is approximately 40°C.
ここで、フィン１４・・・，２１・・・の温度は上記温
度分布に沿って変化している。そして、吐出口２０近傍
では約２１℃の空気に接触することで、凝縮温度が約５
０℃の熱媒が約４５℃まで冷却される。Here, the temperature of the fins 14..., 21... changes along the above temperature distribution. In the vicinity of the discharge port 20, the condensation temperature is approximately 5°C due to contact with air at approximately 21°C.
A heating medium at 0°C is cooled to about 45°C.
このようにアンダークールを増大できるので、より効率
の高い熱交換ができる。Since the undercooling can be increased in this way, more efficient heat exchange can be achieved.
また、このような構造は、吸込口２３．２４を２つ設け
ることで、熱媒の流量が同一であっても熱交換面積を増
大しているので、空気の流量を増大させずに十分な熱交
換ができる。これにより従来構造に比較して高い効率で
熱交換できる。In addition, in this structure, by providing two suction ports 23 and 24, the heat exchange area is increased even if the flow rate of the heat medium is the same, so it is possible to increase the heat exchange area without increasing the flow rate of air. Capable of heat exchange. This allows for more efficient heat exchange compared to conventional structures.
さらに、第１の熱交換部１２と第２の熱交換部１３とに
分割し、空気の流れ方向に沿って上流側と下流側とに配

みとなる。Furthermore, it is divided into a first heat exchange section 12 and a second heat exchange section 13, which are arranged on the upstream side and the downstream side along the air flow direction, and furthermore, the first heat exchange section 12 located on the upstream side is divided into a first heat exchange section 12 and a second heat exchange section 13. A discharge port 20 is provided in the heat exchange section 12, and a second heat exchange section 1 located on the downstream side
By providing the suction port 13 in 3, a counterflow effect is generated and heat exchange can be performed efficiently. Furthermore, each fin 14..., 21 of each heat exchange section 12.13
... are separated by a predetermined gap, so that a slit effect can be generated. In other words, direct heat exchange between the suction side and the discharge side of the heat medium can be prevented, and only heat exchange is performed to the air side.
この結果、少風量でも十分な熱交換ができる。As a result, sufficient heat exchange can be achieved even with a small amount of air flow.
そして、従来構造に比較して同一の熱交換量を得るのに
送風による騒音の低減を計ることができる。In addition, compared to the conventional structure, it is possible to reduce the noise caused by air blowing while obtaining the same amount of heat exchange.
例えば従来構造においては所定の熱交換量を得るために
室内ユニットの前方１ｍの位置で４２ｄＢの騒音が発生
していたが、上述の構造とすることで３５ｄＢに低減す
ることができた。For example, in the conventional structure, in order to obtain a predetermined amount of heat exchange, 42 dB of noise was generated at a position 1 m in front of the indoor unit, but with the above structure, it was possible to reduce it to 35 dB.
なお、本発明は上記一実施例にのみ限定されるものでは

とすることが容易である。Note that the present invention is not limited to the above-mentioned embodiment. For example, higher heat exchange efficiency can be obtained by using an inner ripple tube as the vibrator 15 of the first heat exchanger 12 in which the heat medium flows in a condensed liquid state. Here, the ripple tube has grooves formed on its inner surface to enhance the heat transfer effect. Since the first heat exchange section 12 and the second heat exchange section 13 are separated, they can easily have different pipe structures.

Even if they are not structurally separated, they are included in the present invention. In other words, the same effect can be obtained if there is a thermal isolation structure that reduces heat transfer between the two, such as a cutout structure.
風上側のパイプ径を風下側のパイプより細径化すること
により、騒音を低減する効果を一層だ高めることができ

By providing two or more heat medium suction ports in the heat exchange part of the heat exchanger, the heat of the heat medium flowing in from the suction port is prevented from being transferred to the heat medium on the discharge side.
The efficiency of heat exchange to the passing air can be increased.
また、吸込口を２つ以上設けることにより、熱媒のパイ
プを細径化し、空気の通過に対する抵抗を低減すること
で、空気の通過による騒音を低減できる。Further, by providing two or more suction ports, the diameter of the heat medium pipe is reduced and resistance to the passage of air is reduced, thereby reducing noise caused by passage of air.
これにより、高効率かつ静粛性の高い熱交換器を提供で
きる。This makes it possible to provide a highly efficient and quiet heat exchanger.
